Sinusoidal Filter – CNW933

Sinusoidal output current – save costs and trouble-free operation. For particularly long cable lengths of > 100m between inverter and motor the shielded cable for EMI suppression used can cause a capacitive coupling. A conventional motor choke can not provide sufficient damping in such cases.

REOHM Series 155 – combination

As soon as an electric machine works as a generator (electric motor brake), the braking resistor protects the machine from an excessive voltage increase in the intermediate circuit. REO braking resistors achieve better heat dissipation and better impulse loading by filling heat transport media in the vicinity of the wound body.
